| Abstract | beta-cyclodextrin decorated graphene oxides (beta-CD-GO) was prepared by using an in-situ aggregation treatment, and used to remove inorganic (Pb(II)) and organic pollutants (1-naphthol) from water environment. The batch adsorption experiments of as-prepared beta-CD-GO were carried out as a function of pH values, initial Pb(II) and 1-naphthol concentration, ionic strength, contact time and temperature. beta-CD-GO kinetic results indicated that the adsorption was dominated by chemisorptions and followed a pseudo-second order model. The maximum adsorption capacities of beta-CD-GO toward Pb(II) and 1-naphtholon the base of the Langmuir model were 149.56 and 207.6 mg.g(-1) at 293 K, respectively. The thermodynamic experiments revealed that the adsorption of Pb(II) and 1-naphthol was spontaneous and endothermic. The surface compexation, hydrogen bonds and pi-pi interactions contributed to Pb(11) and 1-naphthol adsorption by means of the hydroxy and carboxyl functional groups on the surface of the beta-CD-GO. The experimental results indicate that the beta-CD-GO is an excellent composite for the elimination of Pb(II) and 1-naphthol from wastewater. (C) 2018 Elsevier Inc. All rights reserved. |
